Low Speed Pre Ignition

Resolving Low-Speed Pre-Ignition. For example, Ford Motor Co. and General Motors Corp. have launched 3-cylinder, 1.0L boosted engines (EcoBoost and Ecotec, respectively) that deliver the same output as their 1.6L 4-cylinder engines, but also provide an approximately 20% improvement in fuel economy and lower CO 2 emissions.

Low-speed pre-ignition. Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions.

Low-Speed Pre-Ignition vs Engine Knock. Engine knock typically occurs at higher revs or when the engine is working hard. Low-speed pre-ignition tends to happen at low engine speeds and higher loads where high fuel efficiency is obtained. Both can cause damage or ultimately ruin a car’s engine.

Low speed pre-ignition (LSPI) is a premature combustion event, occurring prior to spark ignition in turbocharged, downsized gasoline vehicles. As the name implies, it occurs when engines operate at low speeds and high loads. It can result in extremely high cylinder-pressures and can lead to heavy knock.

Unleash Vehicle Performance. Low-speed pre-ignition (LSPI) is a roadblock to better-performing and more fuel-efficient vehicles. Afton Chemical is putting its extensive chemical and engineering expertise, broad R&D capabilities, and global partnerships to action to develop holistic LSPI solutions. The goal: reduce or eliminate LSPI occurrences –...

LSPI is another version of engine knock that occurs in gasoline vehicle engines. ... The latest is a phenomenon called low-speed pre-ignition (LSPI), also known as "super knock," which can destroy pistons and connecting rods. ... it occurs under low-speed, high-torque conditions in turbocharged gasoline direct-injected engines and is more ...

Low-Speed Pre-Ignition. With a recent survey of auto shop owners and technicians, 58% are aware of a problem with the LSPI in car models with turbo charge. The issue is that oil is causing the engine to be more sensitive to low engine speed events.
